The scores of a pre-employment test are normally distributed with mean = 70 and standard deviation = 5. (a) If Y is a randomly selected score, find P(|Y 70|² > 56.25). (b) If only the top 1.5% of the applicants (based on their score on the pre-employment test) are to be considered, find the cut-off score (i.e., the value such that only 1.5% of the applicants score this value or higher).
